Sonochemical Synthesis and Characterization of Some Alkoxyl-Functionalized Ionic Liquids Derived from 1-Butoxyl-3-butyl Imidazolium Bromide

Non-conventional techniques, such as power ultrasound (US) has been used to promote one-pot synthesis of second generation ionic liquids (ILs), reducing reaction times and improving yields. Because of the emerging importance of the ILs as green materials with wide ranging applications and our general interests in green processes such as sonication, 1-butoxyl-3-butyl imidazolium bromide (alkoxyl-functionalized) and their derivatives were synthesized using a facile and green US assisted procedure. Their structures were characterized by FT–IR, 1 H-NMR, 13 C-NMR and mass spectroscopy.
